Crushed gravel is an aggregate frequently used in construction. The stone and aggregate industry creates crushed aggregate using a lengthy process. The stone must be mined in a quarry and then transported to the rock crusher which begins the process of crushing the larger stones into more manageable pieces.
This Part of BS 812 describes a method for the determination of the aggregate crushing value ACV which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.
Mar 30 2021 The aggregate impact test determines the ability of an aggregate to withstand sudden loads. During sudden loads the aggregates may break into pieces. Hence to analyse to provide the adequate quality we perform this aggregate test. Must Read Aggregate crushing test to find strength of aggregate Impact test Relevant codes IS 2386Part 4 1963
Feb 22 2010 The aggregate impact value is a measure of resistance to sudden impact or shock which may differ from its resistance to gradually applied compressive load. Procedure of Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110 C for a period of 4 hours and cooled.

THE DETERMINATION OF THE AGGREGATE CRUSHING VALUE 1 SCOPE The ACV of an aggregate as defined hereunder is determined by crushing a prepared confined aggregate sample under a specified gradually applied compressive load and determining the percentage of the material crushed finer than a specified size.
Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.
